The Rock and Roll Hall of Fame presents All Access: The Story of Rock – Grateful Dead at Watkins Glen

In 1973, Grateful Dead were part of an all-star bill including the Allman Brothers Band and the Band at the Summer Jam at Watkins Glen. When the crowd swelled to more than half a million people, the Grateful Dead made a dramatic last-minute decision, and turned to McIntosh amps to help bring the music to the masses. Rock and Roll Hall of Fame and Museum curatorial director Howard Kramer tells the story.
